Definitions

  • the invention relates to a cutting tool for workpieces made of long-fiber materials, composite workpieces made of multi-layer materials, at least one of which is long-fiber, or the like, consisting of a stationary counter knife, which is formed by a stepped shaped edge, in particular a press-forming tool, and one which is adjustable relative to the latter Knife, which is formed by a mold edge, in particular of the displaceable part of the compression mold.
  • the invention is based on the object to create a generic cutting tool with which a largely orthogonal cut on the edge of a relatively thick workpiece made of foam material and fiber material or only fiber material can be carried out, with the entrainment of fiber material in the cut edge area should be excluded and simple adjustment options possible when the cutting edges wear should be.
  • the invention proposes that the cutting edge of the adjustable knife is formed by a surface which forms an acute angle with the adjustment plane of the knife, this surface being arranged in the cutting position intersecting the cutting edge of the counter knife at an acute angle.
  • This design in which the cutting edge of the adjustable knife is practically formed by an inclined surface that runs onto the cutting edge of the counter knife, ensures on the one hand that the cutting process with respect to the cutting of compressed layers of the workpiece only when the cutting edge of the counter knife hits the inclined surface of the adjustable knife is effected.
  • the counter knife is formed by the edge of an essentially flat mold table which can be overlapped by a hollow mold half which is adjustable towards the latter and whose conical side walls form the cutting surface of the adjustable knife.
  • an adjustable travel limit stop is fixed to the frame, on which parts of the mold half holding the adjustable knife are placed in the cutting position.
  • the path limit stop is preferably arranged so that there is still a short path for the continuation of the adjustable knife as soon as the inclined surface has hit the cutting edge of the stationary counter knife. This slight path corresponds approximately to the material elasticity of the cutting edge or cutting surface that comes into engagement with one another.
  • the adjustable hollow mold half has a projection next to the cutting surface, which has a smaller distance from the mold table than the bottom of the hollow mold half.
  • the workpiece to be trimmed is pressed together in the immediate vicinity of the later interface and thus prepared for the cutting process, so that the cut has an even better quality.
  • a workpiece made of a PUR foam layer 1 and a layer of long-fiber material 2 is inserted into a cutting tool, generally designated 3.
  • the cutting tool consists of a stationary counter knife 4, which is formed by the edge of an essentially flat mold table 5.
  • a knife 6 which is adjustable relative to the latter is formed by a surface which, as indicated at 7, of the knife 6 forms an acute angle with the adjusting plane. In the sectional position shown in the drawing figures, this surface is arranged crossing the cutting edge of the counter knife 4.
  • the surface forming the cutting edge of the adjustable knife 6 is part of a relatively upper hollow mold half 8 which overlaps the mold table 5 on the edge and has conical side walls for this purpose, which form the cutting surface of the adjustable knife 6.
  • an adjustable travel limit stop 9 is fixed to the frame, on which part 10 of the mold half 8 holding the adjustable knife 6 is placed in the sectional position according to FIG. 2. If parts 4 or 6 are worn, it is very easy to readjust by changing the travel limit stop 9.
  • the adjustable hollow mold half 8 has a projection 11 next to the cutting surface 6, which has a smaller distance from the molding tool table 5 than the bottom 12 of the hollow mold half.
  • the material 1, 2 is compressed and solidified in the area of the projection 11, so that a better cut quality can be achieved in the area of the cutting tools 4, 6.
  • the invention is not limited to the exemplary embodiments, but is often variable within the scope of the disclosure.
